If you are developing in the Black Country, getting the light right is rarely optional. Daylight requirements in Walsall sit within an unusual two-layer policy framework: the strategic Black Country Core Strategy, shared with Dudley, Sandwell and Wolverhampton, sitting above a set of saved local policies inherited from Walsall's own Unitary Development Plan. This article explains how those layers fit together, where daylight and sunlight come into the assessment, and what evidence Walsall Council expects to see.
Who decides, and under which plan
Walsall Metropolitan Borough Council is the local planning authority. The development plan for the borough currently has three working parts:
- the Black Country Core Strategy (BCCS), adopted in February 2011 by the four Black Country authorities;
- saved policies of the Walsall Unitary Development Plan (UDP), originally adopted in 2005, a number of which were retained when the BCCS replaced others; and
- the emerging Walsall Borough Local Plan, which the Council began consulting on at draft (Regulation 18) stage from 7 November to 19 December 2025 and which will plan for new homes and jobs up to 2042.
Until the new Local Plan is adopted, the BCCS and the saved UDP policies remain the policies against which applications are determined. The emerging plan is a material consideration but carries limited weight at this early stage.
The amenity and design policies that matter
Three policy references do most of the work where light is concerned:
- BCCS Policy CSP4 (Place-Making) sets the strategic requirement for high quality design across the Black Country, recognising the area's distinctive urban structure and the need for a bespoke, well designed response on each site.
- Saved UDP Policy ENV32 (Design and Development Proposals) is the borough-level design policy used to judge how a scheme relates to its surroundings, including its impact on neighbouring living conditions.
- Saved UDP Policy GP2 (Environmental Protection) is routinely applied by Walsall officers to protect the amenities of nearby residential occupiers from harm such as loss of light, overshadowing, overlooking and an overbearing impact.
Read together, these policies make loss of daylight and sunlight a material planning consideration in Walsall. Harm to a neighbour's light, or poor internal daylight in a proposed dwelling, is assessed under the amenity and design tests rather than against a single fixed figure in the plan.
Local design guidance: the Designing Walsall SPD
Walsall supports its design policies with the Designing Walsall Supplementary Planning Document, adopted in 2013. It provides design and development guidance and is a material consideration when applications are determined, dealing with how new buildings should sit within their context and respect the amenity of neighbours. The borough does not, however, publish its own numerical daylight or sunlight standards.
How daylight is actually assessed: the BRE 2022 method
Because neither the BCCS, the saved UDP nor the Designing Walsall SPD sets bespoke numerical light targets, Walsall relies on the nationally recognised methodology to give those amenity policies practical effect. The relevant technical standards are:
- BRE BR 209, Site Layout Planning for Daylight and Sunlight: A Guide to Good Practice (third edition, 2022);
- BS EN 17037 Daylight in Buildings, cross-referenced by the 2022 BRE guidance for internal daylight provision; and
- the National Planning Policy Framework, which requires good design and a high standard of amenity for both existing and future occupiers.
A BRE-based report for a Walsall site will normally test:
| Measure | What it checks |
|---|---|
| Vertical Sky Component (VSC) | Daylight reaching neighbouring windows, against the 27% benchmark and the 0.8x retained-value test |
| No-sky line / daylight distribution | How far daylight penetrates into affected rooms |
| Annual Probable Sunlight Hours (APSH) | Sunlight to windows facing within 90 degrees of due south |
| Overshadowing | Sunlight on neighbouring gardens and amenity space, tested on 21 March |
For the proposed dwellings themselves, the assessment also confirms that habitable rooms achieve adequate internal daylight using BS EN 17037 illuminance targets.
Typical Walsall situations that call for a report
A daylight and sunlight assessment is most valuable where a proposal sits close to neighbours or where the new units are tightly planned. In Walsall this often arises with:
- rear and two-storey extensions on the borough's densely built terraced and semi-detached streets, where overshadowing of a neighbour's rear windows is a common objection;
- infill and backland plots, where spacing between existing and proposed dwellings is the central amenity issue under GP2 and ENV32;
- flatted schemes and conversions in and around Walsall town centre and district centres such as Bloxwich, Darlaston and Willenhall; and
- any application where a neighbour objects on loss-of-light grounds, or where the case officer asks for a BRE assessment.
Providing a clear BRE report at submission gives the officer the technical evidence to apply CSP4, ENV32 and GP2, and reduces the risk of delay through a request for further information.
